To date, the development of drop-in replacements for the clean agents Halon 1301 and Halon 1211 has eluded the scientific community, despite over 30 years of intensive investigation by hundreds of researchers worldwide and the screening of thousands of candidate molecules.In this lecture we will describe in detail the development of the halon clean agents and their unique combination of physical, chemical, toxicological and fire suppression characteristics, and will also report the results of recent efforts at DuPont to identify the elusive “Son of Halon.” These efforts include the development of new laboratory scale Class A test methods, and the determination of the physical, chemical, toxicological, environmental and fire suppression characteristics of a new class of clean agents.
